I also installed both, but suspect that what you're seeing in the Geomatica 
FreeView is merely a different "gamma curve" - this would enhance some 
detail at the expense of others, so is not a free lunch. :-o

IMO, what we really need is a good recommendation for some software for 
forensic examination and enhancement of our detailed images - not just 
gamma tweaking.

A brand-new image-enhancement technique I've just Googled onto is Retinex - 
has anyone here used this? (It's sold by TruView under the name 
"PhotoFlair") Applying this process to all the VMs sid-files might reveal 
many unseen details:-
